Learning to understand Caitlyn Jenner's transition has been very easy for some, and kind of difficult for most. Although her family supports and loves her through it all, it has been hard for them to adjust to the gender transition, especially when it comes to her voice. Her stepdaughter, Khloe Kardashian, has revealed that she and her sisters, Kim, Kourtney, Kendall and Kylie, have had the hardest time adjusting to the name change, and they do continue to call her "Bruce."

Khloe was on the Australian TV show The Project on Thursday promoting their Kardashian Kids clothing line when she discussed some of the changes the family has made since Caitlyn's decision.

"We don't like to say that Bruce is gone, per se," the 31-year-old reality star said, according to People. "We, my sisters and I, we will call Caitlyn 'Bruce,' and we've been told that's completely fine. She told us we are allowed to call her any name we want to. Because on the phone, when she calls me, it's the same voice as Bruce. And if I'm not physically with her, it's hard to remember in the moment that I'm talking to Caitlyn, if that makes sense."

GLAAD and other LGBQT advocacy groups have warned that it can be considered disrespectful to call transgender people by their original name over their chosen one.. But at the same time, it all depends on what the family feels most comfortable with. The Kardashian/Jenner clan is nothing but happy for her, but Khloe does admit that it was hard for them in the beginning.

"There was a hard time for the entire family, that we are all transitioning with her, but in front of an audience. That's not really the normal way to go about it," Khloe said. "There is a lot of raw emotions, that it's hard to do in front of a camera. For us, we were trying to be really open and raw with it, I think. We all got through it and that's completely over, it's behind us now. So, we are just happy for her. We just want her to be happy. But there was definitely a moment that was really tough for us all."

As for Caitlyn, she realizes her lack of a voice change is going to be hard on people. It's the one thing that hasn't changed in the same way that her appearance has, and she's extremely insecure about it, according to Us Weekly

"Women cannot relate to the whole voice thing," Jenner, 65, says in the upcoming episode of "I Am Cait." "They don't see it as being that important when it is that important, not only for you to speak and order and do all that kind of stuff, but very important for your soul that you're feeling good about that."

Khloe and her sisters never want to disrespect Caitlyn in any way, especially when they call her Bruce, but it's just something that they've been familiar with their entire lives and it's going to take some getting used to, no matter how proud they may be of her.

"It's a beautiful thing that she transitioned," Khloe said.
